Abstract (en)
[origin: EP0955175A2] Printing which accommodates carriage speed non-uniformities by allowing both forward and reverse printing despite the presence of ringing and other overshoot anomalies in carriage printing speed. A determination is made as to whether print data for a current scan and a prior scan overlap in either of two critical zones at lateral extents of the recording medium, where carriage speed ringing and overshoot non-uniformities are most prevalent. If print data for a current scan and a prior scan overlap in either of the two critical zones, the current scan is printed in the same direction as that of the prior scan. On the other hand, if print data for the current scan and the prior scan do not overlap in either of the two critical zones, then printing of the current scan is effected in a direction opposite to that of the prior scan. <IMAGE>
